VC++ 2005 /FC apparently not working

Now, Visual C++ 2005 users out there, the above outputs __FILE__ as a fully qualified path name. The compiler option /FS defines this to be so.

But it's not working. File names keep showing with their full path. I'm wondering why. Some other compiler option affecting it? I can't find on the support site any known issue, so it must be me...
